cBN exhibits a high abrasion resistance and thermal conductivity when compared to conventional abrasives such as Silicon Carbide and Aluminum Oxide.
The thermal integrity of cBN and its ability to maintain sharp cutting edges when machining ferrous materials make it the product of choice in advanced grinding systems.

cBN-BMA
Medium Friability
Angular Shape
Density 3.48 g/cm3
Black, medium strength, with an angular morphology and high thermal stability. The BMA’s angular morphology produces a free cutting action that reduces heat generation and power consumption while increasing grinding efficiency.
- Resin Bond
- Vitrified Bond
- Single Layer Bond
cBN-BMI
Low Friability
Blocky Shape
Density 3.48 g/cm3
Black, medium strength, with a blocky morphology and high thermal stability. The BMI’s blocky morphology provides a more controlled crystal fracture, allowing the tool to better maintain its form while generating smaller particles under impact.

- Vitrified Bond
- Single Layer Bond
cBN-BMO
High Friability
Semi Blocky Shape
Density 3.48 g/cm3
Black, friable, with an irregular shaped morphology. The BMO’s semi blocky morphology produces controlled micro fracturing particles along with free cutting characteristics to enhance wheel life and surface finish.

- Vitrified Bond
- Metal Bond
- Single Layer Bond
cBN-AMA
Low Friability
Angular Shape
Density 3.48 g/cm3
Dark brown, very high strength, with an angular morphology and very high thermal stability. The AMA’s tendency to macro-fracture under impact loading, coupled with its very high thermal stability provides longer wheel life.

- Metal Bond
- Single Layer Bond
cBN-AMB
Very Low Friability
Blocky Shape
Density 3.48 g/cm3
Golden in color, very high strength, with a blocky morphology and very high thermal stability. The AMB’s micro-fracturing characteristics, very high thermal integrity and very high fracture strength produce an aggressive cutting action while retaining the crystal in the bond as long as possible.
- Resin Bond
- Vitrified Bond
- Single Layer Bond
cBN-AME
High Friability
Semi Blocky Shape
Density 3.48 g/cm3
Amber, friable, semi-blocky shape with an irregular crystal morphology. The AME’s controlled free cutting characteristics and consistent fracture mode enhance wheel life and surface finish.
- Resin Bond
- Metal Bond
- Single Layer Bond
cBN-AMX
Very Low Friability
Blocky Shape
Density 3.48 g/cm3
The AMX is a new high strength CBN grit, its blocky shape with sharp edges maintain both its strength and shape across the tool life at the most demanding ferrous metal grinding operations; useful in high speed grinding applications carried out with electroplated CBN wheels.
Resin Bond
systems are widely used for all-purpose superabrasive grinding applications in either phenolic or polyimide bonds. Resin bond systems can be utilized in either wet or dry grinding operations and offer excellent particle retention and part finish.
Vitrified Bond
systems are manufactured from ceramic materials that are strong, durable and brittle. Vitrified bonds are very effective in advanced grinding operations because of their ability to hold the abrasive and reduce heat generation in the grinding zone due to their high porosity levels when compared to other bond types.
Single Layer Bond
systems (electroplated and brazed) hold a single layer of superabrasive grains bonded to a precision machined form. Electroplated systems are bonded with a Nickel matrix and leave approximately 50% of the abrasive exposed while brazed systems leave approximately 80% of the abrasive exposed. Single layer bond systems typically do not require dressing.
